The present embodiment of nay invention comprises a plurality of switchthrowing devices arranged on each side of the switch, a

locking device for locking the device in thrown position, and forinsuring its complete throw, and a hand operating device which normallyis disengaged from the switch.

The switch throwing devices are arranged upon each side of the switch,and are adapted to be operated by suitable mechanism on a moving car,and each of said devices consists of a frame 1 of suitable constructionarranged between the rails 2 and provided at approximately its centerwith a transverse shaft 3, journaled in bearings 1 inside the frame andprovided at one end outside of the frame with an arm 5, whose free endis connected by a plurality of jointed rods 7, with a slide bar 8, to bepresently described, forming a part of the locking device A. Theframe 1. is also provided with a plurality of pairs of shafts or rods 9,having their ends arranged in bearings 10, and having slidable thereon acarriage 11, the carriage being provided at its corners with. sleeves 12which embrace the rods. The carriage is provided near one end with aslot 13, in which engages an arm 1 1, rigid with the shaft 8 beforementioned.

Three different forms of carriage and mounting are shown in Fig. 3 andmore in detail in Figs. 4, 5 and 6. In the form shown in Fig. 4, thecarriage is operated by an independent slide 18, provided at each cornerwith sleeves 19 embracing the rods 9, and spiral springs 20 encircle therods, being arranged between the outer sleeves and collars 21 rigid withthe rods. The slide 18 is provided with a substantial longitudinal slot22, whose front edge is beveled downwardly as at 23, and an operatingarm 24 is journaled in the slot as at 25, the operating arm co1nprisingtwo portions arranged at right angles to each other, one of the portionsbeing adapted to stand upright for engagement by the operating mechanismon the car, and the other end being adapted to lie in the slot, the freeend thereof being beveled to fit the beveled surl'ac 23. ill. platform26 is arranged below the slide upon which the horizontal portion of theoperating arm rests, and the free end of the platform is provided with afriction roller 27. When the vertical portion of the arm 24 is engagedby the operating mechanism on the car, and the slide is moved to theleft of Fig. 4, the arm will remain in the position shown in Fig. 4until the slot passes over the end of the platform, after which thehorizontal portion of the arm will drop downward, permitting thevertical portion to turn into a substantial horizontal position, wherebyto permit the operating mechanism to pass therefrom. Both the carriageand the slide are provided at their abutting ends with abutinents 28 asshown in Figs. 3 and 4.

In Fig. 5, the platform 26 is dispensed with, and the operating arm isretained in operative position by means of a spring 29, and the free endof the horizontal portion is provided with a friction roller 30. Thespring is of sufficient strength to retain the operating arm inoperative position, during the movement of the carriage, but yielding tothe force of the operating mechanism when the carriage steps. In thisconstruction also, the carriage is integral with the slide.

In the construction shown, in Fig. 6, the carriage and the slide areintegral and the arm 14 on the shaft 3 is turned dowmvardly, and anarc-shaped plate 31 is secured to the carriage, the plate being providedwith a slot 32 for receiving the arm. One end of the arc-shaped plate 3is pivoted to the carriage as at 33, and the other arm is insertedbetween the upper and lower members of the bearing or sleeve 12, whichsleeve in the pres ent construction is split as shown in Fig, The frame1 is provided with doors Set, for covering the top thereof, the doorsbeing hinged as at 35 to the frame, and being provided with slots forengaging perforated lugs 36 on the frame, whereby the doors may belocked in closet position. The doors are also provided with slots 37,through which the operating arms project, the slots being of sufficientlength to permit the movements of the arms.

It will be evident from the description, that when the operating arm 24is engaged and moved y the operating mechanisn'i on a moving car, theshaft 3 will be oscillated and through the connection of said shaft bythe rods 7, with the switch operating mechanism, the switch will bethrown.

The operating mechanism comprises a shaft 38, journaled in bearings 39on the cross bars 4. 0, of a frame all arranged beneath the rails 2, andbetween the ties 2 of the track, the said frame being provided with acover 42, hinged as at 41-3 to the frame, and provided with a slot forengaging a perforated lug 44 on the frame whereby to permit the cover tobe locked in place. The shaft is provided each end with an arm as provided with a bearing 46 for receiving the shaft and keyed thereto by akey 47, and the upper end of the arm is slotted as at as, and passesthrough a slot 49 in one of the slidin bars 8 before mentioned, a pintraversing the sides of the slot 48 in the arm 45. The shaft has securedto one end a bevel gear wheel 51 meshing with a bevel gear wheel 52,whose hub 52 is journaled in a bear tongue 61., by means of a channelbar 57 having 1n one of its flanges a series of perforatlons 58 wherebyit may be attached to the point, and provided on its under face with abearing 59 for receiving the switchbar 60,

The top oi the cover is provided with a squareopening 84. for receiving a square nut 85, secured to the shaft 72, by ascrew 86, and the nut 85 is provided with an annular flange 86 which isreceived in a correspondingly shaped recess 87 in the cover whereby tolimit the down ward movement ol the nut. The shalt is verticallymovable, and is normally retained in. its uppermost position by a coilspring 88 which encircles the shaft and bears against a nut 89 threadedon to the shalt, and against the top oi the stand. A handle 88 ispivoted as at 89 to a lug 90 on the cover, and the handle is providedwith a forked portion 91 'l'or receiving the shaft 72, and with abearing surface 92, for engaging the top'o'l. the nut 85 whereby todepress the shaft. The handle is also provided. with a grip 03 forconvenience in manipulating the same, and with a slot 94 for receiving aperforated lateral extension on the lug 90, the perforation. beingadapted to receive a lock 96, whereby to lock the handle in inoperativeposition. A slide 97 is arranged to move transversely of the cover theslide being normally retained in the position shown in Fig. 15 by thecoil spring 98 encircling the same, and bearing at one end against thecover, and at the other against an enlarged portion 99 of the slide, andthe enlarged portion is provided with. a slot which is square at one endas at 100, and round at the other as at 101, and the shalt 72 and thenut 85 pass through the said slot, the nut being provided with a squaredportion 102, for engaging the square end of the slot when the slide isin the position shown in Figs. 16 and 17, whereby to prevent rotation ofthe shaft 72. The outer end of the slide is provided with a lug 103,which is adapted to be engaged by a catch 104; pivoted in the slot 94ol' the handle, so that when the handle is lifted to the position shown.in Fig. 15, the slide will be with drawn a suilicient distance to insurethe disengage ment of the square end of the slot from the square portionof the nut. The slide is also provided with a step 105, for engaging;the cover to limit the outward movement of the slide. it will be evidentfrom the description, that when the handle 03 is lifted into theposition shown in big. 15, and the shaft 72 depressed to disengage thesquare portion 73 from the opening of the hub the locking mechanism andthe switch operating mechanism will be disengaged from the hand operatinmechanism, whereby to perniit the switch to be thrown by hand, byswinging the handle 93 to the right or the left depending upon thedirection in which it is desired to throw the switch. From an inspectionoi Figs. 0 and 15, it will be noticed that the bevel gear wheel 51 isprovided with a hub 106 encircling the shaft 38, and

l retained. thereon by the key 107, and that i the free end. 01' theshaft 38 is journaled in an opening in the bearing 53.

The device is shown as applied to a switch movable in two directions,and three operating devices are shown in position, in Figs. 1 and 2,which as before stated are complementary views, the operating mechanismbeing arranged at suitable distances on each side of the switch. Themain line is provided with an operating mechanism A at the right of theswitch, and an operating mechanism B at the left of the switch, an d anoperating mechanism C is shown on the branch track, each of saidmechanisms being con nected l. the jointed rods 7 with the switch bar60, the said rods moving through. bearings 106 arranged at suitableintervals on the ties. Each operating mechanism is provided with asuitable number of operating arms, sundry of said arms being movable inone direction, and the other arms being movable in the other direction.Mechanism B shown in Fig. 2 is arranged to throw the switch in eitherdirection, and operating by trains advancing toward the switch, and tothrow the switch into closed position as shown in the said figure bytrains moving from the switch, and the mechanism A is arranged to throwthe switch into open. and closed position by trains advancing toward orfrom the switch, while the mechanism. C is arranged to open the switchby trains approaching the same to permit said trains to pass out on themain line and to throw the switch to closed position by trains passingfrom the main line on to the switch.

it will be noticed that the hand operating device comprising the shaft72, and the lever 93 are normally connected with the locking device, andwith the means to be operated by a moving train for throwing the switch,but when. the operating lever is in position for operating the switch byhand, the act of placing the lever in such position disconnects thelocking device, and the train operated means from the hand operatingmeans. This arrangement is for the purpose of permitting the shaft 72which bears a switch light at the rotated by the train operated device,to show the position of the switch to an approaching train, while at thesame time it may be disconnected when it is desired to operate theswitch by hand.

The bearing 106 through which the corn nocting rods slide and shown moreparticularly in Fig. 23, comprises a base 110 which is adapted to besecured to two ties being provided at each end with openings 1.11, andwith lugs 112 on its bottom face, also provided with openings 118, theopenings 111, 113 being adapted to permit the passage of spikes, wherebyto secure the bearing to the ties, the ties engaging the lug 112.Arising top, and a target in the usual manner to be from the base is apedestal 11 1 having integral therewith the lower section 115 of thebearing proper, both the lower section 115 and the upper section 116being flanged as at 11.7, and bolts 118 traverse the flanges forsecuring them together.

The bar 8 slides through bearings 1.19 secured to the ties as at 120,the said bearings comprising a base portion 1.21, having a recess inwhich is received a section 01' pipe 122 formic a friction roller onwhich the bar slides, and an upper portion 123 secured to the lowerportion by the bolts 124.

The locking device is adapted to be arranged between two tics 125 asshown in vFig. 18, and the side plates 126 of the locking device areprovided with laterally extending flanges 127, which extend beyond theadjacent tie, and are provided with horizontal flanges 128 adapted toengage the base 129 of the rail 130, and clamps 131 are bolted to theweb of the rail as at 132, and to the laterally extending portion at133, the clamps having an outwardly bent portion 135 extending aroundthe flanges as shown in Figs. 19 and 20. The laterally extending portion127 is provided with a recess 136 for receiving the rail base, and thetie is recessed as at 137 for receiving such portion.

The frames 1 are bolted to the ties as at 139 and are secured to therails by the clamps 128 before mentioned as shown in Fig. 18.

The connecting rods shown in Figs. 25 and 26, may be provided at one endwith an integral head 140 having a single lug 1&1 or a pair of spacedlugs 142, the lugs being traversed by openings 143, or one 01 the headsmay 7e provided with a hollow internally threaded socket 1 1-1, the end01' theheadbeing threaded into the socket and secured a cotter pin 145,shown in Fig. 26.
